Comfort Controls
This section tells you how to use the comfort controls.
With these systems, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Comfort Controls Personalization
(If Equipped)
If your vehicle is equipped with the automatic comfort
control system and memory seats and mirrors, you
can store and recall the climate control settings for
temperature, air delivery mode and fan speed for
two different drivers. The personal choice settings
recalled are determined by the transmitter used to enter
the vehicle. After the button with the unlock symbol on
a remote keyless entry transmitter is pressed, the climate
control will adjust to the last settings of the identified
driver. The settings can also be changed by pressing
one of the memory buttons (1 or 2) located on the
driver's door. When adjustments are made, the new
settings are automatically saved for that driver.
Manual Dual Zone Comfort Controls
With this system, you can select different comfort
control settings for the driver and passengers.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. You can choose from
five different fan speeds or turn the fan off.
Driver's Side Temperature Lever
The lever on the left side of the climate control panel is
used to adjust the air temperature on the driver's side,
independent of the temperature set by the passenger.
Slide the lever upward to raise the temperature. Slide the
lever downward to lower the temperature.

3-4 Automatic Dual Zone Comfort Control
System (Option)
With this system, you can select different comfort
control settings for the driver and passengers.
Driver's Side Temperature Knob
The driver's side knob is used to adjust the temperature
of the air coming through the system on the driver's
side. Turn the knob counterclockwise to lower the cabin
temperature. The display will show the temperature
decreasing as you turn the knob counterclockwise. Turn
the knob clockwise to increase the cabin temperature.The display will show the temperature increasing as you
turn the knob clockwise. When this knob is adjusted, the
word DRIVER will be displayed under the temperature
setting. If the passenger's set temperature has not been
adjusted, this knob controls both the driver's and
passenger's air temperature.
Passenger's Side Temperature Knob
The passenger's side knob can be used to change the
temperature of the air coming through the system on
the passenger's side of the vehicle. Turn the knob
counterclockwise to lower the cabin temperature. The
display will show the temperature decreasing as you turn
the knob counterclockwise. Turn the knob clockwise to
increase the cabin temperature. The display will show
the temperature increasing as you turn the knob
clockwise. When this knob is adjusted, only the word
PASS will be displayed under the temperature setting.
The temperature to the rear seat area is controlled by
using this knob.
Once this knob is used, the passenger's set temperature
will remain independent of the driver's until the ignition
has been turned off.

3-6
To find your comfort setting, start with a 74
F (23
C)
temperature setting and allow about 20 minutes for the
system to regulate. Turn the driver's or passenger's side
temperature knob clockwise or counterclockwise to
adjust the temperature setting as necessary. If you
choose the temperature setting of 60
F (15
C), the
system will remain at the maximum cooling setting
and fan speed. If you choose the temperature setting of
90
F (32
C), the system will remain at the maximum
heat setting and fan speed. Choosing either maximum
setting will not cause the system to heat or cool any
faster.
Be careful not to cover the sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load, and also
turns on your headlamps.
The EXT (exterior) temperature sensor is located in the
front of the vehicle behind the grille. The displayed
temperature is most accurate after the vehicle has been
moving for a few minutes. If the vehicle is stopped and
then restarted within 2 1/2 hours, the sensor will be hot
from the engine heat. In this case, the temperature first
displayed will continue to be the temperature that was
displayed before the vehicle was turned off. The display
will update after the vehicle has been moving for a few
minutes and the sensor has a chance to cool down to the
actual temperature.To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pushing the fan switch will override this
delay and change the fan to a selected speed.
Manual Operation
You may manually adjust the air delivery mode or fan
speed. Use the mode button to cycle through the
following four air delivery modes:
(Panel): This setting will deliver air to the
instrument panel outlets.
(Bi-Level): This setting will deliver warmer air to
the floor and cooler air to the instrument panel outlets.
(Floor): This setting will deliver air to the
floor outlets.
(Defog): This setting will deliver air to the floor
and windshield outlets.
OFF: Press this button to turn the system off. Some
fresh air will continue to flow through the vehicle from
the floor outlets. The system will try to maintain the
previously chosen temperature setting.

3-8
If your vehicle has the automatic system, in AUTO
mode the system will cool and dehumidify the air
inside the vehicle. Also while in AUTO mode, the
system will maximize its performance by using
recirculation as necessary.
On cool, but sunny days, with the manual system or
through manual operation of the automatic system,
use bi
-level to deliver warm air to the floor and cooler
air to the instrument panel outlets. To warm or cool
the air delivered, turn the temperature control to the
desired setting.
Heating
If you have the manual system, on cold days use floor
with the temperature lever in the red area. If you have
the automatic system, press AUTO and adjust the
temperature by turning the temperature knob clockwise
or counterclockwise. You may also adjust the automatic
system manually by pressing the MODE button and
selecting floor. Again, adjust the temperature by turning
the temperature knob clockwise or counterclockwise.
With either system, outside air will be heated and sent
through the floor outlets. The heater works best if you
keep the windows closed while using it.
Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use front defrost to remove fog
or ice from the windshield quickly in extremely humid
or cold conditions.
If your vehicle has the manual system, select defog and
adjust the fan speed to your comfort level. Turn the air
conditioning on to help dehumidify the air. Use front
defrost with the temperature toward the red area and the
fan control toward high.
If your vehicle has the automatic system and you select
FRONT defrost or defog from AUTO, the system will
control the fan speed. Adjust the temperature and fan
speed to your comfort level. After the windshield is
clear, adjust the temperature to your normal setting and
select the AUTO button and return to AUTO mode and
fan control.
For maximum front defrost performance under extreme
icing or frosting conditions, increase the temperature
setting to 90
F (32
C) and increase the fan speed
to high.

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Setting the Clock

broadcasting Radio Data System (RDS) information,
press and hold HR and MN at the same time for two
seconds until UPDATED and the clock symbol appear
on the display. If the time is not available from the
station, NO UPDAT will appear on the display instead.
RDS clock time is broadcast once a minute. Once you
have tuned to an RDS broadcast station, it may take a
few minutes before pressing and holding the HR MN
buttons will result in an update to the clock time.

Set the volume at the desired level. Press AUTO VOL to
adjust the SCV. AVOL will appear on the display. Each
time you press AUTO VOL, another volume setting
(LOW, MEDIUM, HIGH or OFF) will appear on the
display. The volume level should always sound the
same to you as you drive. Each volume setting allows
for more volume compensation at faster vehicle speeds.
NONE will appear on the display if the radio cannot
determine the vehicle speed. If you don't want to use
SCV, select OFF.
